Since the AFL-NFL merger, these are the NFL teams of decade(s):
1966-1969 = Packers; 66'-67'
1970-1979 = Steelers; 74'-75', 78-79'
1980-1989 = 49ers; 81', 84', 88'-89'
1990-1999 = Cowboys; 92'-93', 95'
2000-2009 = Patriots; 01', 03'-04'
2010-2019 = Patriots 14', 16'-17'?
..notice the back-to-back titles each decade....
Now the patriots, atm, are the only team in the NFL that has won multiple championships in the 2010s... and they might even repeat for the 2017-2018 season giving them 3 NFL championships in the 2010s..... if they do they will be the only team in NFL history to not only be the team of the decade twice but to achieve the feat in back-to back-decades....
